T_e data for [O II], [N II], [S II], and [S III] auroral lines for our galaxy sample in 56 SFR–M_⋆ bins across six different radii. The columns are ordered by ionization zone relations: different low-ionized zones, T_e, are compared in the left panels and low- and high-ionized zones, T_e, are compared in the right. The solid lines indicate the linear fit to error-weighted sigma-clipped temperatures, and the dashed lines represent the one-to-one relation. The shaded regions (σ) represent the standard deviation of temperatures distributed around the fitted values. The number of data points (N°) is specified for each panel, and error bars represent the official temperature errors outlined in Sect. 3.4. The dashed-dotted green and red lines represent the T–T relations introduced by Zurita et al. (2021) and Méndez-Delgado et al. (2023; MD+23), respectively, while the dotted orange line shows the relation reported by Rogers et al. (2021).
